WIRE-STRETGHER AND BUGGY-J'AGK.

Application filed August 2, 1912.

To all whom it may concern:

Be it known that I, ELI. YOUNG, a citizen of the United States, residing at East Auburn, in the county of Placer, State of California, have invented certain new and useful Improvements in Wire Stretchers and Bug, Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention,-such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combined wire stretcher and buggy jack.

The principal object of the invention is to provide a device of the character described which may be either employed for stretching fences or for elevating buggies or other vehicles.

Another object of the invention is to provide a main frame having a carriage movable therealong and a novel means for shifting the carriage and for simultaneously locking the same in any adjusted position along the frame.

A further object of the invention is to provide a device of the character described which is composed of a minimum number of parts, is therefore simple in construction and is cheap to manufacture.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a side elevation showing the device employed as a wire stretcher, Fig. 2 is a rear elevation thereof showing the device employed as a hoisting jack, Fig. 3 is a side elevation thereof, Fig. 4: is a detail longitudinal sectional view taken on the line fl-4: of Fig. 1, Fig. 5 is a detail sectional view through one of the dogs taken on the line 55 of Fig. 1, Fig. 6 is a perspective view of the carriage, the lever and dogs being removed, Fig. 7 is a perspective view of the detachable base, and Fig. 8 is a perspective view of one of the dogs.

Specification of Letters Patent.

Serial No. 712,967.

Like reference numerals designate corresponding parts in all the figures of the drawings.

Referring to the drawings, the invention comprises a main frame A and a carriage B which is slidably mounted thereon.

The frame consists of a pair of spaced parallel bars 5-5 of angle iron construction, which are connected at one end by a cross bar 6, each angle iron including a base flange 7 and a lateral flange 8, the latter being each formed with a series of teeth 9 which extend in a direction'toward the cross bar 6. The cross bar 6 is centrally formed with an outwardly projecting eve 6 adapted for engagement with a chain 10 when the device is being used as a wire stretcher, as shown in Fig. 1 of the drawings.

The carriage B consists of a pair of spaced transversely disposed sliding elements 1111 which are each formed from strap metal. Each slide includes a central portion 12 which is disposed between the lateral flanges 8 of the angle bars and portions 1313 which are formed into bearings for engagement with the base flanges 7 of the bars. The central portions 12 of the elements 11 are connected by a longitudinally disposed support M which operates between the lateral flanges 8 of the bar. The end of the support opposite the cross bar 6 projects beyond the respective sliding element 11, and is formed with an eye 15 for engagement with a chain 16 when the device is used as a wire stretcher.

Centrally secured to the support 14 is a pivot'pin 17 which projects outwardly in the general direction of the teeth 19. Fulcrumed adjacent one end upon the pin is an operating lever 18, said lever extending across the teeth 9 of the bars 5. Secured to the lever 18 on opposite sides of the pin 17 and in alinement with the teeth 9 of the bars 5 are pivot pins 1919. Dogs 2020 are each fulcrumed intermediate its ends upon a pin 19. That end of each dog extending toward the cross bar 6 is formed with a depending tooth 21 adapted for engagement with the teeth 9 of the respective bar 5, and extending downwardly on either side of the tooth 21 are guide fingers 2222, said fingers being disposed on opposite sides of the lateral flange 8 of the respective bar 5. These fingers serve to retain the tooth 21 in engagement with the teeth 9 during the movement of the lever 18. The dogs 20 are fulcrumed upon the pins 19 for not only permitting relative lateral movements between the same and the lever, but also for permitting of a slight longitudinal. move.- ment thereof. The rear ends of the dogs 20 are undercut, as at 23, and secured to the. lever 18 intermediate the dogs 20 is a spring 24. This spring is centrally connected to the. lever by any suitable means, and has its free endseXtendi-ng within the undercut portions 23 ofthe dogs and bearing against the rear end thereof to cause the teeth 21 to be yieldably held in engagement with the teeth 9. Secured to the end of the support 1 1 adqiacent the cross bar 6 isa laterally extending support 25. This support extends beyond the frame A and serves to support an axle of a vehicle (not shown).

When the device is employed for raising vehicles, a base 26' is connected to the free. endsof the side bars 5 by any suitable means. The frame is then positioned verticallyas shownin Figs. 2 and 3' of the drawings.

In operation, when it is desired to use the device either as a wire stretcher oras a lifting jack, the lever 18 is reciprocated and: as a result, the dogs 20 are caused" to successively engage the teeth 9 of the parallel bars 5 and thereby shift the carriage B Copies; of this patent may be obtained, for five cents each, by addressing the Qommissioner' of Batents;

rack bars and adapted at one end for attachment of a wire to be stretched, a lever pivoted upon the bridge piece, pawls. carried by the lever in position to alternately engage.

the rack bars respectively upon actuation of the lever, and a spring arranged onv said lie vet" to yi e'ldinglyretam the pawl's in engagement with the racks, each pawl having'der pending; fingers embracing its rack and be.- ing pivotally movablev with respect to the lever, both in a plane parallel to the plane of movement of the lever andtoward and away from the rack.
